Ortho-Phenylphenol (OPP) is an aromatic organic compound widely used as a technical raw material, specialty chemical intermediate, and functional additive. Known for its stable molecular structure and high purity, OPP provides consistent performance in resin synthesis, dye production, optical materials, polymer additives, and other industrial formulations.

In addition to its value as a chemical intermediate, OPP offers strong antimicrobial and anti-mold properties. It is effective against bacteria, fungi, and mold, making it a useful preservative in coatings, packaging materials, and non-food technical applications. The material appears as a white flaky solid or crystalline powder, featuring a moderate melting point and excellent solubility in organic solvents such as ethanol and ether.

Its chemical stability, versatile reactivity, and reliable structural properties make Ortho-Phenylphenol a multifunctional component for advanced industrial formulations and manufacturing processes.
